Question

以下代码中的client.index(indexRequest)来电：

public static void main(String...sdg) {

    Settings s = ImmutableSettings.settingsBuilder()
            .put("cluster.name","myCluster")
            .build();
    TransportClient client = new TransportClient(s)
        .addTransportAddress(new InetSocketTransportAddress("localhost", 9300));;
    try {
        IndexRequest indexRequest = new IndexRequest("myindex", "pplain", "29");    
        indexRequest.source(makeAJsonDocument("some title", "some content");
        client.index(indexRequest)
              .actionGet();
    } catch (Exception e) 
    { System.out.println("error \n"+e);
    e.printStackTrace();
    } finally {client.close();  
    }
}

抛出以下错误：

Jul 24, 2015 3:40:56 PM org.elasticsearch.plugins.PluginsService <init>
INFO: [Ectokid] loaded [], sites []

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []

我的elasticsearch.yml看起来像这样：

cluster.name: myCluster

我在服务器和Java客户端上运行ES版本1.7.0 - 我只有一个ES安装。

把我弄出来。

我错过了什么？

注意：我看到了ElasticSearch Java API:NoNodeAvailableException: No node available和其他一些帖子。

TIA。

您提供的代码中存在一个小编译问题，请检查您执行indexRequest.source的行，您错过了＆＃39;）＆＃39;。我使用这个代码，它对我来说很好。你能尝试一下吗？你遗漏了一些代码吗？

import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;

public class TestMe {
    public static void main(String... sdg) {

        Settings s = ImmutableSettings.settingsBuilder()
                .put("cluster.name", "performance")
                .build();
        TransportClient client = new TransportClient(s)
                .addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
        try {
            IndexRequest indexRequest = new IndexRequest("myindex", "pplain", "29");
            indexRequest.source("{\"title\":\"This is a title\"}");
            client.index(indexRequest)
                    .actionGet();
        } catch (Exception e) {
            System.out.println("error \n" + e);
            e.printStackTrace();
        } finally {
            client.close();
        }
    }
}

我猜您已经验证群集是否正在使用浏览器运行？ http://localhost:9200
